There are 128.2 g of rubidium (atomic mass = 85.47 amu). Calculate the number of mole? How many atoms are there?
Added by Kenny C.
Step 1
Given: Mass = 128.2 g Molar mass of rubidium (Rb) = 85.47 g/mol Number of moles (n) = Mass / Molar mass Number of moles (n) = 128.2 g / 85.47 g/mol Number of moles (n) = 1.5 moles Show more…
